Enhancement of image data

Abstract

A technology is provided whereby correction may be carried out for both a person's face and other portions of an image, when performing color correction for a photographic image in which a person appears. During color correction of image data of a photographic image, the image data is analyzed, and a first region which is part of the photographic image and in which a person's face is present is determined. Then, on the basis of the portion corresponding to the first region of the image data, a first parameter relating to color is calculated. On the basis of part of the image data corresponding to a second region which is part of the photographic image but different from the first region, a second parameter relating to color is calculated. The color tone of the data is then corrected on the basis of the first and second parameters.

1 . An image processing apparatus comprising:
 a receiving portion that receives from a user an instruction of one of image processing modes including a “human and landscape” mode; and   an enhancement portion that performs an image enhancement on image data according to the received instruction, wherein   the enhancement portion is able to perform image enhancement based on pixel values of one or more faces in the image data and pixel values of one or more objects other than the one or more faces in the image data, the one or more faces being not all but part of faces included in the image data.   
     
     
         2 . An image processing apparatus of  claim 1  further comprising:
 a specifying portion that is able to specify faces in the image data, wherein 
 the image processing modes further include a “human” mode, wherein 
 in a case where the received instruction is an instruction of the “human and landscape” mode, the specifying portion specifies faces in the image data, and 
 in a case where the received instruction is an instruction of the “human” mode, the specifying portion does not specify faces in the image data. 
 
     
     
         3 . An image processing method comprising:
 receiving from a user an instruction of one of image processing modes including a “human and landscape” mode; and   performing an image enhancement on image data according to the received instruction, wherein   the image enhancement is performed based on pixel values of one or more faces in the image data and pixel values of one or more objects other than the one or more faces in the image data, the one or more faces being not at all but part of faces included in the image data.   
     
     
         4 . A non-transitory computer readable medium storing a computer program, the computer program comprising:
 a portion for receiving from a user an instruction of one of image processing modes including a “human and landscape” mode; and   a portion for performing an image enhancement on image data according to the received instruction, wherein   the image enhancement is performed based on pixel values of one or more faces in the image data and pixel values of one or more objects other than the one or more faces in the image data, the one or more faces being not all but part of faces included in the image data, wherein   the image processing modes further include a “human” mode, wherein   the computer program further comprises
 a portion for specifying faces in the image data, wherein 
   in a case where the received instruction is an instruction of the “human and landscape” mode, faces in the image data are specified through the portion for specifying faces, and   in a case where the received instruction is an instruction of the “human” mode, faces in the image data are not specified by the portion for specifying faces.
